Synthesis and complexation properties of fluorescent phenanthridine-basesd calix[4]arene derivates

Calixarenes are macrocyclic oligomers consisted of four or more phenolic residues linked by methylene bridges in the ortho position and can be easily functionalized to give receptors for various ionic or neutral species. Calixarenes bearing fluorescent moieties can be considered as potentially very sensitive fluorimetric ion sensors due to the high sensitivity of fluorescence spectroscopy and high affinity of these macrocyclic ligands towards cations. [1-3] In the scope of this work, novel fluorescent phenathridine-based calix[4]arene derivatives L1 and L2 were designed and prepared (Figure 1) and their complexation properties towards metal cations in several solvents were investigated. Phenanthridine moities were introduced at a lower calixarene rim and served both as fluorescent probes and parts of cation-binding site. Stability constants of the corresponding complexes were determined by means of fluorimetry, UV spectrophotometry, NMR spectroscopy and isothermal titration calorimetry.
